Vision and learning are very closely related. It is estimated that 80% of what a child learns in school is presented visually. So, good vision is necessary for students at any age in order to reach their full academic potential. Spectacles or contact lenses make a huge difference in helping children to see the chalkboard and the books on their desks clearly.
Ruling out simple vision problems is the first step in making sure your child is visually ready for school. However, being shortsighted, farsighted or having astigmatism are not the only visual disorders that can make learning more difficult.
Good vision, requires your eyesight, visual pathways, and brain to all work together. When they don’t, even a person with 20/20 eyesight can experience difficulty reading, writing and processing information.
Most people have the wrong idea that if their visual acuity is 20/20 their vision is normal or perfect. Visual acuity is measured by a person reading a line of letters on a chart. It does not require the same type of eye movements that reading does and therefore cannot be used to determine if a child has the visual skills necessary to read.
Types of Vision Related Learning Problems
Eye health and refractive problems
This includes, shortsightedness, farsightedness and astigmatism and other more serious diseases of the eye.
Functional vision problems
This includes eye teaming (binocularity), fine eye movements and accommodation (ability to focus from near to far smoothly and accurately). Poor functional visual skills can cause blurred or double vision, eye strain and headaches that can affect learning. Convergence insufficiency is a specific type of functional vision problem that affects the ability of the eyes to stay accurately and comfortably aligned during reading.
Perceptual vision problems
This is understanding what you see, identifying it, judging its importance and relating it to previously stored information in the brain. Example, recognizing a word you have seen before and using the eyes and brain to form a mental picture of the words you see.
Symptoms of Vision-Related Learning Problems
- Headaches or eye strain
- Blurred vision or double vision
- Crossed eyes
- Avoidance of reading or close work
- Short attention span with visual tasks
- Closing or covering one eye
- Excessive blinking or rubbing the eyes
- Uses finger when reading
- Slow reading and poor reading comprehension
- Leaving out words or confusing similar words
- Reversal of words or letters
- Poor eye hand coordination
- Evidence of developmental immaturity
If your child shows one or more of these symptoms and is experiencing learning problems, it’s possible he or she may have a learning-related vision problem.
To determine if a problem exists, see an optometrist or ophthalmologist who specializes in children’s vision and learning-related vision problems for a comprehensive evaluation.
If no problem is detected, it’s possible that your child may have a non-visual dysfunction, such as dyslexia or a learning disability. An educational specialist will help rule out these problems.
Treatment of Vision-Related Learning Problems
Treatment generally consists of vision therapy. Spectacles may be given for either full time wear or for specific tasks like reading.
If the child also receives other treatment for a learning disability, all professionals should be in contact with each other in a cooperative effort to address the child’s learning problems and find the best approach in solving the problem.
Also, remember that some children with learning difficulties may have emotional problems as well, such as anxiety, depression and low self-esteem. Reassure the child that learning problems and vision-related learning problems say nothing about a person’s intelligence. Many of these kids have above-average IQ’s and simply process information differently than their peers.Leave a reply
Over half the people over the age of 65 have some degree of cataract development and most cases can be treated with cataract eye surgery. So, if you’re alarmed because your doctor told you that you have a cataract, don’t be. A cataract is a clouding of a part of your eye called the lens.
Your vision becomes blurry because light cannot pass through the clouded lens to the back of the eye. Cataracts can develop over periods ranging from a few months to many years. Sometimes the cataract stops developing in its early stages and vision is only slightly impaired. But if it continues to develop, it will interfere with vision.
The amount and pattern of cloudiness within the lens can vary. If the cloudiness is not near the centre of the lens, you may not be aware that a cataract is present.
Common cataract symptoms:
- A painless blurring of your vision
- Glare or light sensitivity
- Frequent spectacle prescription changes
- Double vision in one eye
- Needing brighter light to read
- Poor night vision
- Fading or yellowing of colours
Misconceptions about cataracts
It is not a growth or film over the eye
It is not caused by overusing the eyes
It is not a cancer, tumor or infection
It is not spread from one eye to the other
It is not a cause of irreversible blindness
What Causes Cataracts to Develop?
Cataracts will usually develop as part of the aging process, but can also result from:
Certain chronic diseases such as diabetes
Long-term, unprotected exposure to sunlight
Previous eye surgery
How are Cataracts Diagnosed?
A thorough eye examination with an instrument called a slit lamp can detect the presence and extent of a cataract, as well as any other conditions that may be causing blurred vision or discomfort. This can be performed by an optometrist or ophthalmologist.
How can Cataracts be Treated?
The cataract may need no treatment at all if the vision is only a little blurry. A change in your prescription may improve vision for a while.
There are no medications, eye drops, exercises or glasses that will cause cataracts to disappear once they have formed. When you are not able to see well enough to do the things you like to do, cataract surgery should be considered. Surgery is the only way to remove a cataract.
When Should Cataract Surgery be Done?
Cataract surgery should be considered when cataracts cause enough loss of vision to interfere with your daily activities. It is not true that cataracts need to be ‘ripe’ before they can be removed. Surgery can be performed when your visual needs require it. You must decide if you can see well enough to do your job and drive safely and if you can read and watch television in comfort.
Also, ask yourself if you can perform daily tasks, such as cooking, shopping, or taking medications without difficulty.
Cataract Surgery Procedure
Surgery on a catatract eye is done under topical anaesthetic, which makes the operation almost painless. The surgeon uses only eye drops to numb the eye completely, no injection or general anaesthesia is necessary.
The procedure used for cataract extraction is micro-incision phaco-emulsification, which involves a sub-2.2mm incision in the side of the cornea, through which the surgeon applies a tiny, high frequency ultrasound instrument. High energy sound waves break up the center of the lens into microscopic particles, which are then gently suctioned out through the incision.
Once cataracts extraction has been successful (after the cloudy lens has been removed), a replacement silicon or alternative intra-ocular lens (IOL) implant, through the 2.2mm incision is added. This new lens allows light to pass through and focus clearly on the retina. The IOL becomes a permanent part of your eye. There are many different IOL’s available to address your specific needs, for e.g. Multifocal IOL’s, Toric IOL’s and Accommodative IOL’s. The surgeon will determine which type of IOL is best suited to your needs. After using this special small incision, you will not receive any stitches.
Surgery does not require an overnight stay in hospital. You will be given eye drops to use for 6 weeks after the operation to prevent infection and reduce swelling of the cornea.
Complications can occur during and after the surgery and as with any surgery, a good result cannot be guaranteed. Infection, bleeding and swelling or detatchment of the retina are some of the more serious complications that may affect your vision, but these are rare. Many patients report immediate improvement in their vision and most return to their normal work and lifestyle routines within a day or two.
What to Expect Long-Term
In some cases, the posterior capsule that supports the IOL becomes cloudy several months or years after the initial cataract removal. This is called “after cataract” or Capsular Sclerosis. If this occurs and blurs your vision, this will be corrected with the Yag laser which is painless and takes about 15 minutes.
Most people who wear bifocals or reading glasses for near vision before cataract surgery will still need to wear glasses after surgery.Leave a reply
LASIK is the most commonly performed refractive surgery procedure. LASIK is short for “laser-assisted in situ keratomileusis.”
It is very popular because it has advantages over other vision correction procedures including a relative lack of pain and that good vision usually is achieved by the very next day.
An instrument called a microkeratome is used in LASIK eye surgery to create a thin, circular flap in the cornea. A newer way of making the flap is with a laser. This flap is then folded back out of the way and then the laser removes some of the corneal tissue underneath and reshapes it.
When the cornea is reshaped it is able to focus light onto the retina, giving you clearer vision than before. The flap is then laid back in place, covering the area that was reshaped.
LASIK can be used to correct short-sightedness, far-sightedness as well as astigmatism.
Before the LASIK Procedure
Your ophthalmologist will first have to determine: if you eyes are healthy enough for the procedure, what type of vision correction will be suitable and also how much laser is required.
Certain conditions like dry eye disease will first have to be treated and cleared up before LASIK can be performed. Also, all health problems and medications you are on needs to be disclosed to the surgeon. Certain health conditions will disqualify you altogether for LASIK, but others may just postpone the procedure for a later date.
Numbing eye drops will be placed onto your eyes so you don’t feel any discomfort during the procedure. You will lie down with your eye directly under the laser.
During LASIK Surgery
An ink marker is used to mark the cornea before the flap is created. The flap is then created with either a microkeratome or a femtosecond laser. You won’t actually see the creation of the flap, which is very thin.
A computer is used to adjust the laser for your particular prescription. You will be asked to look at a target light while the surgeon watches your eye through a microscope as the laser sends pulses of light to your cornea. This will painlessly reshape your cornea. You will hear a steady clicking sound while the laser is operating. You may also smell a mild odor during the laser treatment which is normal.
The higher your prescription is, the longer the surgery will take. The surgeon has full control of the laser and can turn it off at any time.
The actual procedure takes about 5 minutes, and you’re awake the whole time. You walk into the surgery centre, have the procedure done and walk out again. You may receive an oral sedative beforehand.
After the procedure is finished, you will rest for a while. If you are having both eyes done the same day, the surgeon will normally begin working on your second eye immediately after the first. Some people choose to have their second eye done a week later.
Even though the surgery is quite quick, LASIK is a very delicate procedure and it’s important to have it performed by a highly skilled surgeon with proper equipment. You should also have someone accompany you to the surgery centre and drive you home afterward.
As with any kind of surgery, it’s important that you follow your doctor’s instructions. Get proper rest, use all prescribed medications as directed and call your surgeon immediately if you suspect a problem.
You may be able to work the next day, but many surgeons advise a couple of days of rest instead. Also, no strenuous exercise for up to a week an avoid rubbing the eyes.
Most people’s vision improves right away, while others may have a gradual improvement over the next few days or even weeks. Most people achieve 20/20 or better vision after LASIK. Some may only achieve 20/40. Some people still need glasses or contact lenses following LASIK vision correction but their prescription will be lower than what it was before.
Complications can include infection, night glare (haloes around lights at night) and rarely, people will experience clear vision after LASIK, then notice a gradual worsening of vision over time. This is called regression and if this happens, the surgeon will determine if a ‘touch up’ will be necessary.
If you are over 40, you will still need reading glasses for all your near tasks. This is due to presbyopia which is age related.
LASIK Criteria for Success
While many people are good candidates for laser eye surgery, these procedures are not for everyone.
Your eyes must be healthy. With dry eyes, conjunctivitis or an eye injury, you must wait for until the condition is resolved. Eye diseases like cataracts, keratoconus and uncontrolled glaucoma may disqualify you completely.
You must be an adult
Your vision must be stable for at least a year. Vision usually stabilizes in your 20’s. Your optometrist will be able to tell you if your vision is stable.
Pregnancy, affects the fluid levels in your body and this could cause your vision to fluctuate. You would have to wait for your hormone levels to settle down which may take a few months after giving birth.
Degenerative and Auto-immune diseases like Sjogren’s syndrome, rheumatoid arthritis; Type 1 Diabetes, HIV and AIDS will disqualify you.
Your prescription must be within certain limits. Very high short-sightedness, far-sightedness and astigmatism may require a different type of refractive surgery.
Ocular migraines are painless, temporary visual disturbances that may affect one or both eyes. They are usually harmless and disappear within 30 minutes. Medication is not normally required.
Migraine Headache Coming From Your Eyes
If the ocular migraine is followed by a throbbing, headache that is on one side, this is called a “migraine with aura”.
If there is no visual disturbance, this is known as “migraine without aura”.
The aura’s are usually visual, but can affect your hearing, speech or smell. There may also be a numbness or tingling in the face or arms or legs.
Symptoms of Ocular Migraines
You may notice a small blind spot that slowly gets bigger in your central vision.
Flashing or flickering lights or wavy zig-zag lines around the blind spot.
It may last only a few minutes but may go on for about 30 minutes.
Causes of Ocular Migraines
It may be genetic. Most people who get migraines have a family history of migraine headaches.
Migraines are triggered by activation of a mechanism deep within the brain, which releases inflammatory substances around the nerves and blood vessels of the head and brain. Why this happens, and why it gets spontaneously resolved is unknown.
Migraines most commonly affect adults in their 30’s and 40’s, but they may start at puberty and can also affect children. Women are more affected than men.
Certain foods can trigger a migraine attack. Theses include aged cheese, caffeinated drinks, red wine, smoked meats and chocolate. Artificial sweeteners can also trigger an attack in some people.
Other triggers include cigarette smoke, perfumes and other strong smells, bright flickering lights, lack of sleep and stress.
Treatment of Ocular Migraines
Ocular migraines are typically harmless and don’t normally require treatment as they disappear within 30 minutes. If you are driving and an ocular migraine occurs, pull over to the side of the road and rest until your vision returns to normal.
See your doctor if you want advice or want to try to prevent future attacks.
Also, it is very important to make an appointment with your optometrist or ophthalmologist whenever you experience any unusual visual symptoms. This will rule out any sight threatening conditions like a detached retina, which requires immediate attention.
Make a note of the foods you were eating and your activities just prior to the migraine attack to see if you can identify certain triggers and avoid them in the future.
If your migraines are stress related, try eating healthier foods on a regular basis, get plenty of sleep and try relaxing activities like a massage or yoga.Leave a reply
Whenever you walk into any pharmacy or outlet like Clicks, you would have noticed quite a large selection of over-the-counter (OTC) eye drops. This can be very confusing because there are other eye drops which you can only obtain with a doctors prescription.
When Are Eye Drops Needed?
The type of eye drop or ointment you will need depends on what eye condition you have, e.g. dryness, itching, swelling, redness, soreness, allergies or infection. Obviously, when you have an infection of if any of these symptoms are severe, it’s always best to consult your optometrist or ophthalmologist.
Eye Drops for Dry Eyes
Many ordinary OTC eye drops will provide relief for short-term dry eyes, where the eyes get dry when you are tired or spending a lot of time in front of the computer or doing lots of reading. Other causes of temporary dryness include being outside in windy and sunny conditions, on a long flight or if you don’t drink enough water.
Always avoid decongestant eye drops. These are drops that give relief to red eyes. These drops take the redness away but also cause dry eyes. I normally recommend Refresh Tears, Systane or Optive. These can also be used with contact lenses.
Long-term dryness can occur with aging (especially in women), certain medications like diuretics and antidepressants and some auto immune diseases like Sjogrens syndrome. For long-term dry eyes, a gel or ointment may be needed. Refresh liquigel or Celluvisc normally work quite well. Some gels can cause blurring of vision for a few minutes and you may want to use them at night while sleeping.
If OTC drops don’t help, you will need to see your optometrist for dry eye testing and additional treatment.
Eye Drops for Redness
Red eyes can be caused by dryness, allergies, infections, tiredness or a combination of these. Before you use drops for red eyes (decongestants), you should consult your optometrist to determine the underlying cause. Decongestants shrink the blood vessels of the sclera and make the eyes appear whiter. But they mask the cause of the redness. They also cause dryness and irritation if used too often. Also, your eyes may become dependant on them to stay white and clear, forcing you to use them more and more.
If your eyes are red due to dryness or tiredness, I suggest you try a non-preservative OTC lubricating eye drop for relief.
Eye Drops for Allergies and Itching
Itchy eyes are almost always a symptom of an allergy. This will require specific types of eye drops. Sometimes allergies can cause other symptoms like swelling, redness, watery eyes and puffy eyes, for which OTC drops can help.
Allergy symptoms can result from change in season (spring time), or if you are exposed to something you are allergic to. This causes the release of histamines which makes your eyes red, irritated, puffy and sore. And this is made worse by rubbing your eyes. There are various OTC antihistamine eye drops available that treat itching due to allergies by reducing the histamine in the eye tissues. For severe itching that does not improve with OTC treatments, it is best to see your optometrist or ophthalmologist for prescription drops or oral medications.
Eye Drops for Pain, Swelling or Discharge
For any type of eye pain, it is vital to see your optometrist or ophthalmologist first, to determine the underlying cause.
Usually, eyes become sore because they are dry, strained, tired or just overworked. Rubbing your eyes initially feels good, but they will feel worse after a while. A comprehensive eye examination will determine if the soreness is due to a focusing problem related to shortsightedness, farsightedness, astigmatism or presbyopia.
Dry eyes are another common cause of eye pain, which is relieved with lubricating eye drops. These drops may also help with certain types of discharge.
However, thick yellowish discharge caused by eye infections may require a prescription for antibiotic eye drops.
Eye Drops for “Pink Eye” Infections
The common infections most people get are called “pink eye”. Pink eye or conjunctivitis can either be bacterial, viral or allergic. (See article on pink eye.)
If you are using eye drops for eye infections it is important never to touch the tip of the bottle onto your eye. This will contaminate the bottle and spread the infection.
Using the appropriate OTC eye drops can be cheaper and quicker than a visit to your optometrist or ophthalmologist. But rather get them involved instead of being your own doctor. If you are going to gamble, don’t do it with your eyes.Leave a reply
Do you want contact lenses but your parents need convincing? Most parents are skeptical about contact lenses because:
They have never worn them and know nothing about them,
- Or they previously used contact lenses but don’t anymore. In this case they might have some out of date ideas. Contact lenses used to be less comfortable and much harder to take care of in the past.
Or your parents wear contacts now, but they may wonder if contacts are safe for a younger person.
What Teens and Parents Need To Know About Contact Lenses
Here are some common questions I get asked about contact lenses:
How old do you have to be to wear contact lenses?
There is no age limit. Babies can wear them, and so can seniors. Most optometrists will encourage contact lenses from the age of 8 years. You just need to be responsible enough to take care of them.
Why not just wear glasses?
Teen are self-conscious, and often feel more attractive and accepted if they don’t have a pair of glasses in front of their eyes. Contact lenses give you greater self-esteem and you feel more at ease around others. They also offer a great advantage with all types of sport.
How much care do contact lenses require?
All you need is one bottle of multipurpose solution and a case. Certain types of contacts like dailies don’t need to be cleaned because you will throw them away at the end of the day.
Do you need a prescription to get contact lenses?
Yes. A contact lens is a medical device and it must be fitted properly on the eye. If not, serious eye infections can occur. This is true even for colour or cosmetic contact lenses. This is why they must be fitted by an optometrist, who will measure the proper size, shape and power of the lenses.
If I have astigmatism or a strong prescription, do I have to wear glasses instead?
Not anymore. These days, contact lens designs are able to correct all types of vision problems including astigmatism.
Are contact lenses comfortable?
Modern lenses are very soft and you don’t even realize that they are in your eyes. Also, your optometrist has specialized equipment to measure your eyes and make sure the lenses fit comfortably.
What about colour contacts?
These colour contact lenses are fun and safe, just as long as they have been fitted and prescribed by an optometrist. Never buy them online or anywhere else without a prescription. And never share them with your friends. Serious eye infections can be passed along this way.
What if contact lenses just don’t work out?
Sometimes, your optometrist may feel that contact lenses are not the best option for you now, but it may be in a year or so. If this is the case, you can always go back to wearing glasses and re-try contacts later on.
So educate your parents today and they might want contact lenses for themselves and for you!Leave a reply
A good comprehensive eye test does more than just determine your prescription for glasses or contact lenses. Your optometrist will check your eyes for common eye diseases, assess how your eyes work together as a team and evaluate your eyes as an indicator of your overall health.
The Importance of Eye Exams
Your optometrist will check:
- Refractive Error. This will determine if you are short sighted, far sighted or have astigmatism.
- Amblyopia. Often called a “lazy eye”. If left untreated, a “lazy eye” can result in permanent vision impairment.
- Strabismus. This is a crossed eye or turned eye. Your optometrist will check the alignment of your eyes to make sure the two eyes work together.
- Eye Teaming Problems. Sometimes the eyes don’t work together as a team. This will result in headaches, eyestrain and can affect reading and other near vision tasks.
- Focusing Problems
- Eye Diseases
Who Should Get Their Eyes Examined?
Everyone. Adults need to get their eyes tested to get their current pairs of spectacles updated and to check for early signs of eye disease. Children need to get regular check ups to ensure normal visual development and for academic achievement.
Vision is closely linked to the learning process. Children who have difficulty seeing or interpreting what they see will often have trouble with their schoolwork. Often, children will not complain of vision problems simply because they don’t know what “normal” vision looks like.
If your child performs poorly at school or has a reading or learning disability, be sure to have his eyes examined to rule out an underlying visual cause.
Treatment after your Eye Exam
After your eye exam, your optometrist will either prescribe spectacles, contact lenses or vision therapy depending on the results.
No matter who you are, regular eye exams are important for seeing more clearly, learning more easily and preserving your vision for life.
Don’t delay. Schedule an appointment with your optometrist now!Leave a reply
Do you think your colour blind? Do you find it difficult telling if colours are red and green, or blue or yellow? Do other people sometimes tell you that the colour you think you are seeing is wrong?
If so, these may be signs that you have a colour deficiency, which can be called colour blindness.
What is Colour Blindness?
Colour blindness is actually an incorrect phrase, as it is not a form of blindness at all. Rather, colour blindness is a deficiency in the way you perceive colours. With this problem, you have difficulty seeing colours such as red and green or blue and yellow.
Red-green colour deficiency is the more common type. It affects about 2-6% of all males. It is very rare in females.
Blue-yellow colour deficiency is very rare, but affects both males and females equally.
People who are colour blind don’t necessarily see the world in shades of grey. They are able to see a full range of colours, but certain colours appear very different or appear less pronounced than what a person with normal colour vision would see.
If you suddenly develop a colour vision problem where you could previously see a wide range of colours, you should consult your optometrist or ophthalmologist. This could be due to other underlying health problems.
Colour Blindness Test Video
Causes of Colour Blindness
Colour blindness occurs when light sensitive cell in the retina (called cones) fail to respond appropriately to certain wavelengths of light that allow us to see colour. There might be a deficiency in these cones or a complete lack of them. This is normally inherited, so most people with colour blindness are born with it.
It is a neurological disease so light sensitive cells may be damaged and results in colour blindness.
The lens becomes cloudy causing hazy vision and colours appear less bright. Cataract surgery will normally restore colour vision in this case.
Tiagabine for Epilepsy
This medication has been known to reduce colour vision, but its effects are not permanent.
Retinal cells can be affected as we age, decreasing our colour vision.
An injury to the back of the head could also result in colour blindness.
Treatment for Colour Blindness
Unfortunately, there is currently no cure for colour blindness.
Gene therapy has been successful in curing colour blindness in monkeys, but this has not been proven to be safe in humans as yet.
Most people who are colour blind adapt quite well but others have their career choices slightly limited. If you had to consider a career as a graphic designer or an electrician, you would be required to have very good colour vision.
If you become aware of your colour blindness at an early age, you can plan and train for your profession that does not require you to have a full range of colours.
Diagnosing colour vision problems early in life may also prevent learning problems as a lot of learning material at a younger age is dependant on colour perception. If your child is colour blind, the teacher needs to be aware of the problem so he/she can plan the lessons accordingly.
For adults, you can always work around your colour vision problems, like organizing your clothes in a certain order or labeling them to prevent colour clashes. Wearing 2 different coloured socks can be quite embarrassing. So get someone to help you.
Make sure you visit your optometrist or ophthalmologist if you need more advice on colour vision or if you’ve noticed problems in your children.Leave a reply
Eye twitching or eyelid spasms are quite a common occurrence. Your eye twitch usually occurs only on the bottom eyelid, but sometimes the upper eyelid can also twitch. Most eyelid twitches come and go. Sometimes your eye twitch may last for weeks and sometimes months.
Today we will look at the question “why does my eye twitch” and help explain to you the causes of eye twitching, when it is serious and when it is not, and some of remedies for your eye twitch.
Causes of Eye Twitching
These eye twitch muscle contractions can be caused by:
Almost all forms of eyelid twitching are not serious but they are difficult to treat. The only form of eyelid twitching treatment is to figure out what causes the twitching and deal with it.
More serious forms of eyelid twitching are caused by neurological conditions like:
- Blepharospasms or,
- Hemifacial spasm.
These are less common and should be treated by an eye specialist.
Why Does My Eye Twitch?
Eye Twitch Videos[youtube=http://www.youtube.com/watch?v=jn12P-IvZJ0]
Stress: we are all under stress at times and our bodies react differently to stress. Eye twitching can be one of the signs of stress, especially if related to vision problems like eyestrain. Reducing the eyestrain can cause the twitching to stop.
Tiredness: a lack of sleep can trigger eye twitching. Catching up on some sleep can help.
Eyestrain: Vision related stress can occur if you need glasses or need a change in your glasses. Your eyes may be working too hard to give you comfortable vision and this will trigger eye twitching. Computer eyestrain is a very common cause of vision related stress.
If the eye twitching is persistent and irritating you should have an eye exam, because you may need vision correction. If you spend a lot of time in front of the computer, your optometrist may prescribe special computer glasses.
Caffeine and Alcohol: Research has shown that increased alcohol and caffeine consumption can trigger eye twitches. So, if your alcohol or caffeine (tea, coffee, cold drinks) consumption has increased, try to cut down.
Dry Eyes: Dry eyes are very common among the older population. Dry eyes are also common among computer uses, people taking certain medications (antidepressants, antihistamines), contact lens wearers and people drinking a lot of alcohol and/or caffeine. If you are tired and under stress, you may also get dry eyes. This can all lead to eye twitching. It is best to see an optometrist for dry eye evaluation as there are a lot of treatment options available.
Nutritional Imbalances: Some studies have shown that a lack of certain nutritional substances like magnesium can trigger eyelid twitching. However there is no scientific evidence of this. So always consult your doctor before adding magnesium supplements to your diet.
Allergies: Eye allergies result in itching, swelling and tearing. Rubbing the eyes, causes the release of histamine into the lid tissues and tears. It has been shown that histamine can cause eye twitching. Some doctors recommend antihistamines for eyelid twitching. However antihistamines can cause dry eyes. So it’s best to consult with your eye doctor for the best treatment for your eyes.
Eye Twitching Remedies
Most of the time time is the remedy needed with eye twitches going away on their own.
In rare cases the eye twitching just does not go away. Some of these can be treated with botox injections which will stop the muscle contractions.
Always see your optometrist or ophthalmologist immediately if the twitching affects half your face or the entire eye, causing the lids to clamp shut.Leave a reply
The food we put into our bodies can have a huge impact on our eyes, especially later in life. Here is basic guideline on what we should be eating more of and what to avoid.
Specific antioxidants like vitamin A protects against night-blindness and vitamin C may help prevent glaucoma.
Essential fatty acids have been shown to help with dry eyes as well as macular damage. Read on to find out more.
Nutrition and the Eye
The following foods provide excellent nutrition for the eyes:
- Vitamin A: cod liver oil, carrots, livers, butternut squash
- Lutein and Zeaxanthin: spinach, kale, collard greens.
- Vitamin C: sweet peppers (red or green), kale, strawberries, oranges and broccoli.
- Bioflavonoids: citrus fruits, cherries, grapes and plums.
- Vitamin E: sunflower seeds, hazel nuts and almonds.
- Selenium: Brazil nuts, yeast and sea food.
- Zinc: oysters, hamburgers, wheat, nuts.
- Fatty acids: cold water fish (salmon, mackerel and trout).
In general, we should eat lots of leafy green vegetables, two servings of fish per week, some nuts and lots of orange fruits and vegetables.
Too much bad carbs can be harmful to your eyes. It causes your blood sugar to spike and this can be harmful to your eyes. Also, too much bad carbs can increase your risk of developing macular degeneration.
Healthier carbs like high fiber fruits and vegetables are much better. Enjoy!Leave a reply
